Abstract
The utility model provides a gas heat exchanger which is used on a gas water heater, comprising a housing and a heat collector arranged on the housing, wherein, the heat collector comprises a plurality of root of heat collecting pipes and tens blocks of heat collecting slices. The utility model is characterized in that a plurality of welding holes are respectively arranged on the corresponding parts of the tens blocks of heat collecting slices, a welding fabrication hole is arranged on and communicated with each welding hole, the plurality root of heat collecting pipes are respectively inserted in the corresponding welding holes arranged on the tens blocks of heat collecting slices, and the plurality root of heat collecting pipes are connected to integration with the heat collecting slices by adopting gas shielded welding; besides, the inlets and the outlets of the plurality root of heat collecting pipes are connected in series into a connected body. The utility model has the advantages of strong performance of oxidation resistance and anticorrosion, long service life and little pollution to environment.
Description
The utility model relates to a kind of gas heat exchanger that is used in the gas heater.
The existing heat collector that is used for the heat exchanger in the gas heater is formed by thermal-collecting tube and heat collecting sheet series connection expand tube, adopts the method for dip-coating leypewter to be coated with the last layer leypewter on its surface.The leypewter fusing point is low, easily fusing, evaporation, and,, influence presentation quality even also easy to change in atmosphere to human body, big for environment pollution.After using a period of time, heat exchange effect reduces, influences service life.The red copper material that heat collector adopts, red copper oxidation in the time of 200～400 ℃ is quite fast, and thin-walled, thin walled shell at high temperature corrosion resistance, oxidation resistance reduce, and influence service life.Because what welding manner adopted is the gas welding of acetylene-oxygen, heating surface area is big, and thin walled shell is yielding, and oxidation decortication when welding, solder flux in welding process because of gas pressure spatters and creeps to Sifang District, dangerous.
In view of above reason, the purpose of this utility model is in order to overcome above deficiency, provide a kind of anticorrosive, oxidation resistance is strong, long service life, the gas heat exchanger that environmental pollution is little.
The purpose of this utility model is achieved like this: the utility model comprises housing; place the heat collector that contains several thermal-collecting tubes and tens of heat collecting sheets on the housing; it is characterized in that on the tens of heat collecting sheet correspondence positions several welding holes being arranged respectively; the welding process hole that is communicated with is with it arranged on each welding hole; several thermal-collecting tubes are through in the corresponding welding hole on the tens of heat collecting sheets respectively and adopt gas shielded arc welding that itself and heat collecting sheet are connected to integral body; advancing of several thermal-collecting tubes; outlet is concatenated into connected component successively (referring to Fig. 1～Fig. 4); when heat collector is installed; several thermal-collecting tubes are through in the corresponding welding hole of tens of heat collecting sheets; welding rod is through on the welding process hole; adopt gas shielded arc welding; flowing to space between welding hole and thermal-collecting tube after the welding rod fusing fills up it and thermal-collecting tube and heat collecting sheet is welded together; because adopt gas shielded arc welding, the material of thermal-collecting tube and heat collecting sheet can adopt oxygen-free copper; stainless steel; aluminium.
The window (referring to Fig. 1) that outside protrusion is arranged on the above-mentioned housing has been avoided being out of shape in combustion process with the igniting nail joint and has been touched.
During the work of the utility model heat collector, cold water is entered by water inlet pipe, to the heat collector thermal-collecting tube, circulate through the burning die cavity with coil pipe, flame is in burning die cavity internal combustion, burned flame and flue gas are by the narrow space between thermal-arrest organ pipe, sheet, realize the exchange of heat, with the heating of the cold water in the pipeline, hot water flows out from another outlet pipe then.
Compare with existing heat exchanger, the utility model heat exchanger has following advantage:
1, thereby because fruit has used the welding process hole that communicates with welding hole can adopt gas shielded arc welding, thermal-collecting tube and heat collecting sheet is integrally welded, heat exchanger material can adopt oxygen-free copper, stainless steel, aluminium, so anticorrosive, oxidation resistance is strong, and is high temperature resistant, durable in use, long service life;
2, do not need the dip-coating leypewter, do not produce plumbous steam, safe in utilization, to the human body nonhazardous, environmental pollution is little;
3, adopt gas shielded arc welding, avoided zero, parts oxidation decortication loss in process, good looking appearance;
4, the pipeline circulation is long, and heating surface (area) (HS is big, the water temperature height, and flow is big, has improved the thermal efficiency, energy savings;
5, adopt the evagination window, avoided touching in distortion of combustion process middle shell and igniting nail joint, prolonged service life.
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is the collector structure schematic diagram.
Fig. 4 is the A-A cutaway view of Fig. 3.
Fig. 5 is the welding process hole location drawing 1.
Fig. 6 is the welding process hole location drawing 2.
Fig. 7 is the welding process hole location drawing 3.
Referring to Fig. 1～Fig. 4, heat collector 1 places red copper housing 2.In the tens of oxygen-free copper heat collecting sheets 3 in the heat collector 1 between sheet and sheet parallel and distance equate.Several welding holes 4 are arranged respectively on the tens of heat collecting sheet relevant positions, the welding process hole 5 that is communicated with is with it arranged on each welding hole.The several thermal-collecting tubes 6 that adopt oxygen-free copper to make are through respectively in the welding hole on the tens of heat collecting sheets and with gas shielded arc welding thermal-collecting tube and heat collecting sheet are welded as integral body.The import and export of several thermal-collecting tubes are unified into connected component in twos.The import of connected component is connected its outlet and is connected with outlet pipe 9 with the coil pipe 8 that contains water inlet pipe 7.Raised type window 10 is arranged on the housing 2.
The position of welding process hole and welding hole relation also can be as Fig. 5～shown in Figure 7.
Claims (2)
1, gas heat exchanger; comprise housing, place the heat collector that contains several thermal-collecting tubes and tens of heat collecting sheets on the housing; it is characterized in that on the tens of heat collecting sheet correspondence positions several welding holes being arranged respectively; the welding process hole that is communicated with is with it arranged on each welding hole; several thermal-collecting tubes are through in the corresponding welding hole on the tens of heat collecting sheets respectively and adopt gas shielded arc welding that itself and heat collecting sheet are connected to integral body, and the import and export of several thermal-collecting tubes is concatenated into connected component successively.
